Uhaul Wine/Beer Shipping boxes
Safely ship wine or beer bottles with the Wine Shipping Kit. All kits come complete with a protective styrofoam base and lid and include the shipping box. The protective styrofoam base will fit wine or champagne bottles up to 4″ in diameter (standard and universal bottles). Kits are available to ship 1, 2, 3, or 6 wine bottles at one time.http://www.uhaul.com/MovingSupplies/Boxes/Kitchen-moving-boxes/Wine-Shipping-Kits?mid=169

Helpful Hints
Prevent Breakage, Then Prevent Leakage – The key to successfully shipping beer is to get them to their final destination unbroken. That means packing them well and stuffing the box with lots of padding so the beers won’t shift around in the box. This is your first line of defense. But sometimes things go wrong, despite your best efforts, and a bottle might break. When that happens, you want to keep the spill contained and to stop it from leaking through the box. When a box starts to leak, it gets pulled out of shipping process. Often the box gets thrown away by the shipping company, despite the fact that the rest of the bottles in the box might be fine.

Tips on how to ship beer
Use a sturdy double-walled box, or put one box inside another. Old or new plastic cooler(use duct tape to seal)
Use plenty of filler material. Packing peanuts and bubble wrap work best.
Make sure no glass is touching.
Make sure nothing moves when you shake the box.
Use styrofoam wine shippers for the best and easiest way to ship.
Tape
Write fragile on the box (though I’m not convinced this makes any difference whatsoever)
Write “liquid yeast samples” on the box (sort of true).
Try to package the beer so that the recipient can reuse the packing materials.
Line the box with bubble wrap or foam.
Ship beer via UPS or FedEx using an online account and print your shipping label at home. Don’t use USPS.
